Cluster Bomb Strain

In many ways, clusters bombs are the worse weapons of mass destruction used. In fact, it has killed way more people than the two infamous bombs dropped in Japan. So, naming a strain after such terrible weapons must come with good reason.

Regardless of the background story, one thing is for sure. The breeder of Cluster Bomb, Bomb Seeds, always name their strains using the word bomb.

In reality, the infamous name is suggestive of its effects. In laboratories, its THC content ranges from 15% to 20%. In other words, Cluster Bomb is at the least an above average hybrid. At best, it comes with insane potency.

Cluster Bomb is known for delivering an intense and buzzing cerebral high. It is complemented by an incredible relaxing body high that typically does not lead to a couch-lock.

As mentioned, the original breeder is Bomb Seeds. Using a legendary strain called Cinderella 99, they crossed it with an original Skunk No. 1 from Sensi Seeds. Its offspring is then crossed with the breeder’s Bomb No. 1. As such, Cluster Bomb took some of the best traits of its parents.

Although it is listed as being a balanced hybrid, it is actually an Indica-dominant strain. Such traits are what also made its parents famous in their own rights. For instance, Skunk No. 1 is known for its high-energy mental buzz. Meanwhile, Cinderella 99 is notable for its dreamy and uplifting effects, as well as its high yield.

    One way to describe the destructive force of cluster bombs is that it is evil. Does it sound too ominous? In fact, the strain does come with its baggage. Due to its potency, beginners may want to especially take it easy.

    At its onset, it detonates and rushes in an uplifting sensation that not only causes people to feel happy but also euphoric. At the same time, the intense mental buzz may come off as feeling a little hazy, but nonetheless, users remain clear headed. A boost in energy complements the heightened sense of focus as most users are still able to finish their tasks.

    After a few minutes, its Indica side starts to creep down. It soon envelopes the whole body in a relaxing sensation. Even in such a relaxed state, users tend not to be bound to wherever they are sitting or lying down.

    As is the case with any marijuana, overindulging leads to strains overwhelming users. As such, it is important to remember to use within one’s own tolerance or limit.

    Should some people happen to use it too much, then it is likely that the buzzing mental high can cause people to feel dizzy. At the same time, any hope of doing anything comes to a halt as one is bound to be locked on the couch.


    Instead of smelling death, Cluster Bomb actually has a gentler scent that most people will find appealing. It emits a sweet skunky odor with a hint of earth and citrus. As soon as the buds break, it also emits a slightly pungent odor.


    Not only does it smell good, but it also tastes delightful. Cluster Bomb has a sweet taste that has a refreshing blend of berry and citrus. In effect, users love its aftertaste and the smoothness of its smoke.

      Generally, Cluster Bomb is not a hard cannabis hybrid to grow. Bomb Seeds sell only excellent quality seeds, as such, the quality of its plants should be at least above average. Of course, that is assuming that growers know what they are doing.

      Flowering Time


      Like most Indica plants, it will reach its flowering stage in as early as seven weeks. We do recommend letting it stay in vegetative phase for another week or two. Afterward, once harvest time comes, growers can expect at least 24 ounces of buds.


      Each Cluster Bomb plant produces a whopping 28 ounces if grown outdoor. By the last days of September, it should be nearing its flowering stage.
